# Classical Mechanics

## Hardcore training for the aspiring physicist.

Here we'll establish the bedrock principles of physics and use them to reveal matter in motion; from drones and rockets to skyscrapers and blinking fireflies.

By the end, you'll develop a rigorous approach to describing the natural world and you'll be ready to take on new challenges in quantum mechanics and special relativity.
